FEED-TRO UGH.

SPECIFICATION forming part of Letters Patent No. 477,724, dated June 28, 1892. Application filed September 17, 1891. Serial No. 405,973. (No model.)

' invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The special object of the invention is to make an automatic feedingcrib for hogs, as hereinafter described.

Figure 1 of the drawings is a front elevation of the crib with its doors thrown open; Fig. 2, a vertical longitudinal section thereof; Fig. 3, a vertical crosssection.

In the drawings, A represents the crib, which may be made of sufficient dimensions to contain one-or two hundred bushels of corn in the car. In. the bottom of this crib I arrange hoppers B, whose side and rear walls incline downwardly to acentral bottom, while the front wall remains perpendicular and contains the hole a and interior hood a, the latter projecting over said bottom,so that the ears of corn will roll under the hood by their own gravity and within reach of a hog standing on the platform 0. The latter is pivoted at the rear to and between the projecting beams D D and may be supported in front on a spring E, so that it will be depressed in front by the weight of the animal, thus moving up or down a vertical rod F, which slides in the guides G G. To this rod F is connected one or two doors H, which cover the holes a. by means of the end pivoted rods I I, the said doors being corner-pivoted to the crib at a short distance from the rods. By this combination and arrangement of parts a hog is enabled to open a door leading to one of the corn-hoppers and take out an ear of corn whenever he may feel hungry, while' as soon as he steps oif the platform the door will be closed and the corn in the crib protected from the Weather.

J J are guides on the crib for receiving the doors as they move up and down. The crib may have a suitable roof, and there may be one platform and one vertical rod F for each one or every two of the doors, holes a, and hoppers B. K are end openings for medicine, &c.

Having thus described allthat is necessary to a full understanding of my invention, what I claim as new, and desire to protect by Let ters Patent, is-

An automatic feeding-crib for swine, provided with the openings to, hoods a, hoppers B, corner-pivoted doors H, vertical rods F, pivoted arms I, connecting the rods F with the doors II, and the rear pivoted platform 0, supported in front on the spring E, all substantially as shown and described.

In testimony whereof Iaffix lnysignature in presence of two witnesses.
